The Tin Can Tools Flyswatter and Flyswatter 2 have a FT2232H
with a  JTAG interface wired to port A. The buffers that drive the
JTAG pins need to be enabled with an nOE signal from the
FT2232H ADBUS6 and ADBUS7 pins.

Flyswatter has an ARM-14 JTAG interface and Flyswatter 2 has

When multiple dediprog programmers are connected, the 'id' parameter
allows you to specify which one to use. The id is a string like SF012345
or DP012345. The value is printed on a sticker on the back of the dediprog.

This is an improvement over the 'device' parameter which is based on
enumeration order and changes when you plug/unplug devices or reboot the
machine.

To find the id without the sticker, run flashrom with the -V option.
This prints the ids as they are enumerated.  Alternatively, with dpcmd,
you can use the --list-device-id and --fix-device commands to list and
write device ids respectively.

Note this only supports SF100 at the moment, but SF600 support is
possible with more work.

Since fread() returns the number of bytes read, this currently will only

is possible for fread() to encounter an error after reading a few bytes,
which this doesn't catch. Fix this by using fgets() instead, which will
return NULL if EOF or an error is encountered, and is simpler anyway.
